I used Calman up until they went to 4, and I could not stand it. I also had issues with my Chroma 5 and felt the software to be lacking. At the recommendation from someone trustworthy, I went to Chromapure a few years ago and never looked back. Tom is also an easy guy to get ahold of and is very frank when you ask "should I upgrade to this meter is is the one I have just fine".
I have been hearing Calman 5 is quite nice though.
